A B S T R A C TThe objective of this study was to determine the photochemical efficiency of 'Gigante' cactus pear cultivated under different spacings and bovine manure doses in the semi-arid region. The experiment was conducted in a randomized block design in a 4 x 3 x 7 factorial scheme, with three replicates. The first factor consisted of four doses of organic fertilization (0, 30, 60 and 90 Mg ha -1 year -1 of bovine manure), the second one, of three spacings (1.0 x 0.5, 2.0 x 0.25 and 3.0 x 1.0 x 0.25 m) and the third one of seven reading times (6, 8, 10, 12, 14, 16 and 18 h). Chlorophyll a fluorescence readings were taken in cactus pear cladodes in the dry and rainy seasons using a pulse-modulated fluorometer. Cladodes of 'Gigante' cactus pear cultivated under different spacings and bovine manure doses undergo changes in photosystem II during the dry season under the physiographic conditions of the semiarid region in Bahia. During the rainy season in the semi-arid region, the photosynthetic yield in cactus pear cladodes is considered ideal.Eficiência fotoquímica em cladódios de palma forrageira 'Gigante' cultivada sob diferentes espaçamentos e adubação orgânica R E S U M OObjetivou-se determinar a eficiência fotoquímica da palma forrageira 'Gigante' cultivada sob diferentes espaçamentos e doses de esterco bovino na região semiárida. O experimento foi conduzido em blocos ao acaso em esquema fatorial 4 x 3 x 7, com três repetições. O primeiro fator foi constituído de quatro doses de adubação orgânica (0; 30; 60 e 90 Mg ha -1 ano -1 de esterco bovino), o segundo, por três espaçamentos (1,0 x 0,5; 2,0 x 0,25 e 3,0 x 1,0 x 0,25 m) e o terceiro por sete horários de leitura (6; 8; 10; 12; 14; 16 e 18 h). Foram realizadas leituras de fluorescência da clorofila a em cladódios de palma forrageira nas épocas seca e chuvosa com auxílio de um fluorômetro de luz modulada. Os cladódios de palma forrageira 'Gigante' cultivada sob diferentes espaçamentos e doses de esterco bovino sofrem alterações no fotossistema II na época seca nas condições fisiográficas do semiárido baiano. Na época de chuvas na região semiárida o rendimento fotossintético em cladódios de palma forrageira é considerado ideal.

“…The photosynthetic efficiency of cladodes is expressed by the net assimilation rate (NAR), which is directly related to the plant's growth habit, in which initially there is less shading that provides greater photosynthetic efficiency. The authors of [48], evaluating CO 2 assimilation methods in Opuntia ficus-indica plants, found that shading was responsible for a 50% reduction.…”

Supplementary irrigation can be strategic for forage cactus, aiming to guarantee higher levels of productivity and economic return. Therefore, this study aimed to evaluate the growth dynamics, productivity, evapotranspiration, and water economy indices of three forage cactus clones under different water regimes. The study was carried out in the Brazilian semi-arid region during two cycles between 2020 and 2022. Clones of forage cactus Orelha de Elefante Mexicana—OEM (Opuntia stricta (Haw.) Haw.) were evaluated; IPA Sertânia—IPA and Miúda—MIU (both species Nopalea cochenillifera (L.) Salm-Dyck) were subjected to four water regimes: rainfed and three irrigation depths (4, 8 and 12 mm). Growth dynamics and evapotranspiration were evaluated throughout the cycles, and productivity and water economy indices were based on data from the harvest time. The OEM clone showed higher dry matter productivity (21.8 Mg ha−1). The MIU clone, when intended for seed sales, presented a higher economic return (USD 20,823.33). The use of irrigation brought forward the cutting time and reduced water saving rates. With this, it can be concluded that the increase in water availability in cactus increases water consumption and reduces economic-water indices but brings important productive returns.

“…In the cactus-sorghum intercropping system, the higher yield of the forage cactus under the east-west orientation compared to the northsouth (see Table 4) may be related to the greater light capture of plants in east-west orientation, which directly contributes to their development (Peixoto et al, 2018), on the other hand, plants in north-south row orientation suffer shading caused by the sorghum crop on the cactus. Crop shading in intercropping systems can reduce the incidence of light on the smaller crop, causing a reduction in photoassimilates and, consequently, a reduction in the productivity of the shaded crop (Franck et al, 2013;Almeida et al, 2014). This directly influences plant physiology and results in lower levels of chlorophyll compared to plants in full sun (Texeira et al, 2020;Jardim et al, 2021b).…”
